well, you already know how to convert from mixed to improper, so let's simply do the multiplication, as it's very straightforward.


\bf 4\frac{2}{7}\cdot 2\frac{1}{5}\implies \cfrac{30}{7}\cdot \cfrac{11}{5}\implies \cfrac{30}{5}\cdot \cfrac{11}{7}\implies 6\cdot \cfrac{11}{7}\implies \cfrac{66}{7}\implies 9\frac{3}{7}

What are the steps to solve 4p-3=-9+7p
weeeeeb [17]

Answer:

p = -4

Step-by-step explanation:

So first of all, you need to combine like terms. In order for that to happen, you need the like terms on one side. You get rid of a number by adding ( if subtraction), multiplying (if division), and subtracting (if addition) by its reciprical. Since it is a negative 3, you add it. Whatever you do to one side, you have to do to the other. That leaves us to 4p = 9 + 7p +3 or 4p = 12 + 7p. Since 7p is positive, you have to subtract from both side leaving us with 4p - 7p = 12 or -3p = 12. You then divide both sides with -3 to isolate the variable leaving us with p = -4
